WKLLIAM A. TRAVER, OF PROVIDENCE, RHODE ISLAND,' ASS IGNOR T0 FRANKLIN RAYON DYEING COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND BIPARATUS FOR DYEING ANDDTHERWISE PROCESSING FIBROUS MATERIALS Application filed September 9, 1926. Serial No. 134,438.

This invention relates to apparatus for dyeing and otherwise processing fibrous materials. such as artificial silk and rayon.

The invention is particularly directed to improvements in the apparatus described and illustrated in the co-pending ap'plication for U. S. Letters Patent Serial N 0. 134,451 filed September 9, 1926. The application referred to discloses means for supporting and holding units of hollow dye-cops or packages.

arranged in series inaxial alinement with separators intervening between their ad]a cent ends.

One object of the present invention is to provide an improved form of separator plate or flange which acts automatically to aline the packages as they are assembled in series and to center them with respect to the skewer or standpipe on which they are stacked, while thereafter maintaining their axial openings properly spaced therearound.

Further objects of the improvement are set forth in the following specification which describes a preferred embodiment of the invention as illustrated by the accompanying drawings. In the drawings:'

Fig. 1' is an axial sectional view of a unit or stack of dye-cops or packages shown as assembled in series on a central standp ipe and illustrating the present improved separator platesor flanges intervening between the adjacent ends 0 the cops;

Fig. 2 is a perspective view of the improved separator; and 3 Fig. 3 is a sectional view thereof.

Referring to Fig. 1 of the drawings, 2 designates the dye-cops or packages of iibrous material, such as artificial silk, rayon and the like, which are wound in cylindrical form on rigid, perforated tubes or holders 3. The tubes 3 are preferably covered with sleeves 4 of fabric or other reticulated ma-.

terial to provide a roughened-surface on their" exterior which holds the coils of windin in place, thus permitting the strand materia S to be wound-clear to the ends of the tube. In this Way the packages are wound with their fiat ends flush with the ends of the tube in the manner as more particularly described in theco-pending application above referred to.

by way of example only, these elements not vterial in accordance with the improved method set forth in the application referred to the cops orpackages 2 are assembled in series in axial alinement to provide units or stacks for application to the dyeing kier. Preferably, the several cops in each unit are strung on a stringer or skewer in the form of a perforated standpipe provided with end flanges 8 and 9 between which the material is confined. Conveniently, the bottom flange 8 is screwed onto the lower end of the standpipe 7 and fastened with pins 10, while the upper flange 9 is adjustable on the opposite end of the pipe. For this latter purpose a threaded plug 11 is inserted into the upper end of the pipe 7 and fastened in place b screws 12' with the flange 9 arranged to be p aced on its projecting portion and clamped against the end cop of the series by means of a ring-nut 13. (0 It is to be understood, however, that the form of construction of the cop-holder, stringer or "standpipe and other parts of the dyeing apparatus as above described areherein illustrated being essential to the present invention.

It is explained in the co-pending application above referred to that for dyeing artificial silk, rayon and other fibrous materials of the same nature it is necessary to confine the dye-co s at their ends to prevent the packages rom bulging or bursting under the pressure of the circulating fluid, and to also separate the ends of the packages in the stacks or units so that the fibers may not be matted or crushed together to injure the filaments. In accordance with the disclosure in the co-pending application referred to a relatively thin plate or disk is employed .as a separator between the adjacent ends of the several packages in the stack or unit. The plate is preferably of circular form with an opening at its center to adapt it to slide lon- 'gitudinally of the standpipe 7. In the present invention I make use of a separator 15 of the general construction as above described, the same being constituted in a relatively flat circular disk as illustrated in perspective in Fig. 2. The disk or flange 15 has an axial opening 16t0 adapt it to be 1"" slipped on over theend of the standpipe 7 and to he slid longitudinally thereof into position to intervene between the adjacent ends of successive packages or dye-cops 2 arranged in the unit as illustrated in Fig. 1. As before indicated, the present improvement relates particularly to means embodied in the separator to adapt it to aline the dye-cops in position and to maintain them in concentric relation with respect to the standpipe 7. For this purpose I provide the separator flange or disk15 with a plurality of circumferentially-disposed prongs or'lugs 17 projecting.

from the opposite faces of the flange to adapt them to enter within the open ends of the cop-tubes 3 on which the packages are wound.

, Conveniently, the lugs 17 may be constructtheother three will project on the opposite sideas illustrated most clearly in Fig. 3. The

number and arrangement of the lugs may be varied as desired, but I have found that the present;v construction provides a most eflicient device for the purpose intended.

As each pac age 2 is placed in.the unit a separator 15 is applied to its end before the next package is placed on the stringer or standpipe 7. In carrying out this procedure the placing of the separator 15 performs the function of locating the hollow dye-cop or package 2 concentric with the stringer 7- through the engagement of the lugs 17 in the open end of the cop-tube 3. The lugs 17 are slmply inserted into the end of the coptube overlying the inwardly folded or tucked-in end of the fabric slee've 4; The three lugs on each side of the plate or flange 15 provide a three-point bearing for the tube 3 to hold the package from canting or rocking laterally of the standpipe 7. Now, when the next package 2 is slid down on the standpipe 7 the upstanding lugs 17 on the opposite side of the separator 15 willbe introduced intothe end of the cop-tube 3.to aline this package with the previously placed one and to hold both packages with their tubes 3 concentric with respect to the standpipe7. In this manner,'- as each successive. cop or ackage is added to the series it is brought into concentric relation and held in alinement with the other packages. Finally, the end flange 9 is placed against the topmost cop or package 2 in the stack or unit, and it will be noted that this flange has a projectin boss or hub 19 which enters into theend of the cop-tube 3 to centralize this last package.

as a holding or bracing means to prevent the w column of material from buckling between its ends. That is to say, the individual packages are positively retained concentric with respect to the standpipe 7 by means of the separator disks or flanges 15 and the tubes 3=will be prevented from canting or rocking so that one package cannot become displaced with relation to the neighboring ones. The central openings in the packages, that is the space defined by the inner tubular supports for the masses of material, are maintained concentric with the standpipe 7 through which the dyeing liquor or other fluid flows. Therefore, a uniform channel is maintained so that the pressure of the fluid will be constant as it circulates from the standpipe 7 radially outward through the perforations in the tubes 3 and thence into the mass of material surrounding the tubes. In this way my improvement not only provides for greater ease and convenience in placing the dye-cops in position, but also makes for a more eflicient functioning of the dyeing apparatus under and during the circulating process.

While I have herein described and illustrated a preferred form of construction of the device it is to be understood that various modifications may be made therein without departing from the spirit or scope of the .in-

vention.

Therefore, without limiting myself in this respect, I claim:

-1. Adevicefor use in confining the ends of hollow cops or packages of fibrous materials in subjecting the same to dyeing or other processes comprising asheet-metal plate adapted to set against the end of the package and provided with a central open-- ing with prongspunched from the metal surrounding the opening to form projections on its side adapted to-enter the opening in the end of the package.

2. A separator for confining the mass of fibrous material in hollow cops or packages while subjecting. the same to dyeing or other processes COIDPI'lSIXlg a plate-like member adapted for insertion between the relatively flat ends of ad acent packages to contact with the material therein whereby to prevent them from bulging at their ends and the fibers in one package from inter-mingling with those of another package, and means on said member for engaging the central openings in the packages to maintain them in axial alinem 1 :J.

In testimony whereof I aflix my signature.
